The fact that the writer was willing the take such abuses indicates that he is doing it because there are no other people willing to employ him on the same amount. In that sense, he isn’t really “underpaid”. To be fair a lot of employees in MNCs are working from home even though they are supposed to be on MC or recuperation, so I dun think this is a unique SME problem.

Anyway how much is he paid as an operations manager? If it’s above 2.5k employment act does not apply to him.
